The present invention addresses at least the above-described issues witha system that offers climate control, and optionally other processing,in separated compartments that hold items in removable and/or lockablecontainers that may be individually climate-controlled. In addition tothese basic functions, the system can integrate functions for notifyingusers of important events. Examples include, but are not limited to,sensor readings that indicate spoiled food, temperature changes outsidea desired range, containers not opened or removed within a predeterminedtime period, etc. In one preferred embodiment, different processingoptions for items stored in the compartments are integrated into thesystem. Examples of advanced processing include, but are not limited to,heating (thawing, cooking), pressurizing or depressurizing containers,physical movement of items (vibrating, turning content in thecontainer), etc.

The present invention is preferably an integrated unit that can storeand process perishable and non-perishable items in a variety of ways.The unit preferably integrates functions in addition to refrigeration,such as a freezer, an ice unit and/or an oven, and has multiple separatecompartments that can be individually controlled for temperature,humidity, pressure, and/or other conditions. The unit may freeze,refrigerate, thaw, warm, heat, cook, pressurize, depressurize, and/orotherwise process items in each compartment separately. The unit couldalso have hot and cold water and other beverage dispensing compartment.The unit may also incorporate various forms of robotics for furtherautomation of the system. Items are preferably inserted and stored inthe unit by use of removable containers, which may be locked into thecompartments to prevent unauthorized access.

The present invention is not limited to processing of food items inoffices or residences. Other applications for the present inventioninclude, but are not limited to: (1) use in laboratory environments,where probes can be exposed to a variety of environmental conditions;(2) storage solutions and/or vending units for delicate items thatrequire climate control; and (3) commercial use in restaurants, schoolcafeterias and others.

Potential benefits of the present invention include, but are not limitedto:

-   -   Eliminate food theft because food is secured in boxes that only        the user has access to;    -   Eliminate uncertainty as to whether food items are bad, expired        or forgotten through the use of smart technology systems and        sensors;    -   Eliminate moldy, smelly refrigerators;    -   In an embodiment of the present invention that integrates        multiple processing functions, space can be saved by eliminating        the need for separate units to perform the respective functions.        For example, one embodiment of the present invention could        incorporate the functions of a microwave, toaster oven, ice unit        and dishwasher;    -   Energy savings through compartmentalizing space and cooling        and/or heating only occupied spaces;    -   In one embodiment of the present invention, rapid and energy        efficient cooling and heating through vacuum cooling and        induction heating;    -   In one embodiment of the present invention, the ability to both        heat and cool each individual compartment;    -   User interactive—individual users can set times, temperatures,        alarms, etc. for their respective compartment; and    -   Employers can track and evaluate the use of the unit via data        reporting.

Possible applications for the present invention include, but are notlimited to:

-   -   A refrigerator with lockable compartments for use by individuals        in offices, dormitories, or similar settings;    -   A refrigerator/freezer with lockable compartments and with food        preparation functionality (e.g., thawing, warming, heating,        cooking), for use by individuals in offices, dormitories or        similar settings;    -   A storage unit for delicate beverages (e.g., wines, cognacs,        etc.) that require climate controlled storage. Temperature and        humidity in each compartment can be individually. Each        compartment may optionally have a mechanism that allows slow        rotation of a bottle in the compartment;    -   A storage unit for cigars which allows for the storage of        various types of cigars under different conditions (in separate        compartments), and also allows access control (e.g., for shared        humidors);    -   A multifunctional unit that may integrate compartments with        different features, thereby allowing for the storage of wines,        cigars, and/or other items within one unit;    -   A unit for a laboratory setting that allows probes to be exposed        to different environmental conditions, such as, for example,        physical movement (e.g., shaking, vibrating, stirring etc.). The        environmental conditions in each compartment can be individually        programmed and monitored through use of sensors, actuators, and        controllers integrated into each compartment or container;    -   A vending unit for prepared food items. Such units can keep food        items refrigerated and quickly warm or heat items before        dispensing them;    -   Transportation—commercial/business aircraft and cruise        ships/yachts could use the present invention for meals and        beverages;    -   Restaurants can use the present invention for individual special        food entrees and storage of those entrees, beverages, cigars and        vending units;    -   Restaurants, bars & clubs could utilize the refrigeration        feature of the present invention for specific bottle service at        exact temperatures and/or full bottle service ownership, whereby        a customer that buys an entire bottle and/or mixers for the        night could store the bottle at a chilled temperature in a        locked cabinet that only that purchaser can open to retrieve the        bottle and/or mixers;    -   Restaurants/bars and/or clubs could also incorporate an        embodiment of the present invention on a larger scale that could        robotize the commercial restaurant and bar industry by allowing        the customer to order their food through an application on their        smartphone prior to arrival. The system would find and cook        their meal to order and could even deliver said food and        beverage via robotics to the table without ever needing a        waiter, thereby eliminating a substantial cost burden to the        restaurant owner. It would automate the order, preparation,        delivery and cleanup of plates and food items. Behind the        scenes, the restaurant cooks and/or robots could prepare the        food in the specialized trays and place them into the oven;    -   Schools, ski lodges, arenas and cafeterias could incorporate the        present invention both as a unit used behind the kitchen line,        and a unit that is used in the main area of the restaurant for        customers to use with their own food or purchased products. One        example is a school cafeteria whereby students could place their        food into a locked compartment and set a precise time for        cooking/chilling the food items (such as their lunch hour) so        that it is ready when the school bell rings. Another example        behind the kitchen lines is utilizing the invention as a        multi-stacked grouping of robotic line cooks able to handle a        high volume of students for lunch service. All of the meals        could be timed to be cooked to perfection at a predetermined        time. Once the unit is unloaded, another load could be placed        into the unit for the next group of people;    -   Pharmacies, hospitals, doctors, veterinarian offices, etc. can        use the present invention for medicine and/or biological items,        such as blood, organs etc.;    -   Coffee houses can keep bulk coffee beans vacuum packed and under        correct temperatures for better preservation of the beans; and    -   The present invention can be used to create and store/maintain        dry ice.

FIG. 1 is a schematic diagram illustrating the compartments 10 andremovable containers 20 of a unit 100, in accordance with one embodimentof the present invention. The unit 100 can be as simple as a standardrefrigeration unit that has been compartmentalized for targeted use inoffices, dormitories, roommate scenarios, home use, etc. Such a unit 100could either be created by converting existing refrigerator models toallow installation of separate compartments or through a newrefrigerator design.

FIG. 2 is a schematic diagram illustrating the conversion of an existingrefrigerator model to allow for separate compartments 10, in accordancewith one embodiment of the present invention.

FIG. 3 is a schematic diagram illustrating a refrigerator design withcompartments 10 of different sizes, in accordance with one embodiment ofthe present invention. The installation of a frame in conventionalrefrigerators may impede the flow of cold air. As a result, thetemperature may differ between compartments 10. One way to address thisissue is to design the frame such that it incorporates ventilationshafts, ventilation openings, and air guards as required to direct theflow of cold air to each compartment.

FIG. 4 is a schematic diagram illustrating one possible implementationof such a frame where cold air flowing above the frame is directed byair guards down the air shafts of the frame into individualcompartments, in accordance with one embodiment of the presentinvention.

One advantage of the present invention is that it can be implementedusing conventional refrigerator designs. However, a disadvantage ofimplementing the present invention using conventional refrigeratordesigns is that it does not allow for individual climate control andfull separation of compartments. As a result, rotting food in onecompartment may affect items in other compartments. Another embodimentof the present invention addresses these shortcomings.

Additional embodiments of the present invention preferably comprise oneor more of the following:

-   -   a unit housing that aggregates, electrical components, and        electronic components;    -   aggregates for temperature control (e.g. compressors);    -   optional aggregates for pressurizing/depressurizing compartments        (e.g. vacuum pump);    -   pipes for climate control of individual compartments (e.g.,        cooling circuits, air pipes, etc.);    -   a frame within the temperature controlled section of the unit        that divides the available space into multiple compartments and        insulates compartments from each other;    -   sensors, actuators, fittings, and interfaces that connect each        compartment to the main unit aggregates, electrical system, and        electronic system;    -   removable containers that that can be inserted into the        compartments; and    -   locks that lock a container into a compartment, allowing only        authorized users to remove the compartment—the locks are        suitably key locks, magnetic locks, electromagnetic locks or any        other type of lock.

In one preferred embodiment, each compartment can be individuallycontrolled for environmental conditions. Examples of environmentalconditions include, but are not limited to, temperature, pressure,humidity, and lighting. To achieve that level of control, eachcompartment preferably connects with the unit's aggregates (e.g. coolingsystem, vacuum pump, etc.), the unit's electrical systems, and theunit's central processor. Compartments preferably do not share piping,i.e., each compartment preferably has its own pipes to the aggregates.This eliminates cross-contamination between apartments (e.g., rottenfood).

Connectors for piping, electric, and electronic components arepreferably positioned in the back wall (backplane) of each compartment.Compartments are preferably designed to accept containers with matchingfittings at the (container) backplane. Seals provide proper insulationand air-tight connections for piping when a container is inserted into acompartment.

FIG. 5 is a schematic diagram illustrating an example of a compartment10 with fittings for cold air 110 and 112, pressurized/vacuum line 120,and humidifier/de-humidifier line 130, in accordance with one embodimentof the present invention.

FIG. 6 is a schematic diagram illustrating a container 20 for thecompartments 10 with matching connectors 140, in accordance with oneembodiment of the present invention.

This configuration allows for different types of refrigeration.Conventional cooling lines enable the flow of cold air through thecompartments. The vacuum line 120 allows for rapid cooling using vacuumcooling. A variation of this embodiment may implement other coolingmethods, such as those described below.

The humidifier/de-humidifier line 130 is preferably used in conjunctionwith cooling and vacuum to control the humidity level in thecompartment. Thawing, heating, and cooking within a compartment 10 maybe accomplished through induction heating or other heating methods, suchas those described below.

For induction heating, the bottom of each compartment 10 is preferablymade of a glass or ceramic plate 141 (or other suitable material) withmetal wires 142 underneath that can generate an alternating magneticfield, as shown in FIG. 7. The wires are connected to the unit'selectrical system through the backplane 140 and the flow of electricityis preferably controlled by the unit's central processor 150 or by alocal processor 160 within the compartment (e.g., for direct loop-backwith sensors to avoid overheating in case central processor crashes).

The central processor 150 or local processor 160 is preferably a specialpurpose computer, programmed microprocessor or microcontroller andperipheral integrated circuit elements, ASICs or other integratedcircuits, hardwired electronic or logic circuits such as discreteelement circuits, programmable logic devices such as FPGA, PLD, PLA orPAL or the like. However, the central processor 150 or local processor160 may also be implemented with a small embedded computer system withintegrated sensors, such as a smartphone running the iOS or Androidoperating system. The central processor 150 or local processor 160 mayalso be implemented with a modular electronic platform, such as theRaspberry Pi platform, or a proprietary embedded system with integratedsensors and actuators.

Induction heating allows for both cooling and heating of items within asingle container 20 (e.g., food items stored in stainless steel lunchboxes within a container 20 could be heated through induction heating,whereas items in plastic or glass boxes (or bottles) within that samecontainer are not heated and remain cold).

Containers 20 can be subdivided into cold and hot storage areas toensure proper separation of cold and hot items (e.g., to keep plasticbottles away from the hot surfaces of the stainless steel boxes). Thiscan be achieved through removable inserts that divide the availablespace in a container 20.

The inside of containers 20 may be made of silicon-based materials towithstand extreme temperatures (e.g., during heating). The advantages ofsilicon-based materials in food storage and food preparation have beenwell documented. Other applications (e.g., laboratory settings) mayrequire different materials.

Compartments 10 are preferably insulated from each other sufficiently toallow cooking of food under pressure in one compartment 10, whilerefrigerating items under low pressure in an adjoining compartment 10.To achieve the proper level of insulation, the frame's thickness andmaterial composition is preferably chosen according to the specificrequirements (min/max temperature, min/max pressure, etc.).

Sensors within each compartment 10 or container 20 are preferably usedto measure the environmental conditions of the compartment and thestatus of the content. Sensors may include, but are not limited to,ambient air temperature sensors, light sensors, pressure sensors, lasertemperature sensors (e.g., for measuring temperature of content), pHsensors for measuring the pH level of content, and/or gas-detectingsensors that can identify rotting food. Any currently available orfuture sensor technology may be integrated.

The unit's central processor 150 preferably controls the environmentalconditions of each compartment 10 based on sensor data it receives fromeach compartment 10 and user defined configuration parameters (e.g., setvalues such as desired temperature, pressure, humidity, etc). These setvalues may also be derived from programs or algorithms and may changeover time. For example, food can be kept refrigerated until noon andthen warmed or cooked. Special food items (e.g., prepared food forpurchase) may come with programs and/or algorithms for storage andpreparation. Such programs and/or algorithms may automatically be loadedinto the central processor 150 by means of RFID tags or othertechnologies and methods as soon as a food container is inserted intothe compartment.

Compartments 10 preferably have a locking mechanism that preventsunauthorized users from accessing containers 20. Under certaincircumstances the central processor 150 may unlock a specificcompartment 10 automatically, giving all users physical access to thecontainer in that compartment 10. This may happen, for example, whensensors detect rotting food in a compartment 10 or when the maximumstorage time for a compartment 10 has expired.

The central processor 150 preferably controls access to compartments 10by requiring identification and authentication of users. Suitablemethods for identification and authentication include, but are notlimited to, badges, biometrics (e.g. fingerprint), number combination(e.g., pin), passwords, RFID tags (e.g., RFID bracelets) or any otherexisting or future devices/methods. Preferably, only authorized users(compartment owners or system administrators) can program,electronically monitor, and/or physically access compartments 10.

Authorized users preferably have access to one or more of the followingfunctions:

-   -   downloading and execution of programs and algorithms that        control the compartment's environmental conditions, including        physical movement of its content (e.g., turn, shake, vibrate,        etc);    -   locking/unlocking a compartment;    -   configuration of access rights (who else has access to the        compartment);    -   configuration of alerts; and    -   access to real-time alerts and alert logs.

Users preferably interact with the unit's central processor 150 by anymeans that currently exists or may exist in the future. Examplesinclude, but are not limited to, keyboard & monitor, touch-screen, cardreaders, keypads, or other devices mounted on the unit or connected tothe unit. Connected devices may include, but are not limited to,enterprise components (HW, SW) or personal devices like tablets,smartwatches and eyewear, such as Google Glass® or smart phones.

The central processor 150 can preferably send real-time alerts to usersthrough these interfaces. A user may, for instance, receive an SMS,e-mail, and/or social media notification when the temperature orhumidity in their compartment 10 is outside a set target range. Somealerts may be sent to all users of the unit, not just the compartmentowner. Such events may include, but are not limited to, notificationsabout bad or expired food items in a compartment 10 or alerts related tothe whole unit, such as power outages or aggregate failures. A moredetailed list of alerts that may be implemented is provided below.

The unit's central processor 150 may be connected to enterprise systemsto allow integration into enterprise databases and applications viaenterprise services buses or other technologies.

Special Purpose Compartments

Special compartments 10 are optional compartments that a unit 100 may ormay not have depending on the unit's configuration. Special compartments10 may offer additional functionality such as, for example:

-   -   cleaning and sanitizing containers;    -   special food preparation;    -   beverage dispensing;    -   ice dispensing; and    -   other purposes.

Any of these special purpose compartments 10 could be combined with anoptional vending or payment apparatus to allow for payment via variousforms including cash, credit card, online payment processors (e.g.,through mobile devices), or any other form of payment.

Cleaning Compartment

This is a special purpose compartment 10 for cleaning and sanitizingcontainers. When a container 20 is inserted, the compartment ispreferably locked and a treatment program automatically starts. When theprogram is finished the compartment 10 is unlocked.

For example, if food in a container 20 goes bad (which could beindicated by sensor alarms) then the food compartment 10 is preferablyautomatically unlocked and all owners of other compartments 10 in thatunit, as well as unit administrators and operators, are preferablynotified. Any of these individuals can remove the container 20 with thebad food item, empty the contents out, and then insert the containerinto the sanitation compartment. Once inserted, a cleaning programpreferably starts automatically. When the cleaning program is finished,the compartment 10 is unlocked and the container 20 can be removed andreused.

In one embodiment, the cleaning compartment 10 may allow users to placean empty but dirty container upside down into the cleaning compartment.The cleaning compartment 20 may use pressurized heated water or asanitizer mixer to blast out the contents and clean the container 20.

In one embodiment, the movement of containers to and from the cleaningcompartment may be a manual process (i.e., a user places the dirtycontainer in the machine and removes it when it is clean). In anotherembodiment, the container movement may be implemented through anautomated, robotic process.

Food Preparation Compartments

A food preparation compartment 10 may suitably be:

-   -   a pizza oven;    -   a toaster;    -   a steamer;    -   a microwave; and/or    -   any other current or future food preparation mechanism.

If the heating and cooling offered by the standard compartments is notenough, then containers can be moved to the above-listed specialcompartments for food preparation.

Beverage Dispensing Compartments

Beverage dispensing compartments dispense hot or cold beverages likesodas, water, coffee, milk, alcohol, etc. They can be used in a varietyof environments, from workplaces (typically coffee, milk, hot & coldwater) to bars (e.g., self-service beer dispenser with payment module).

Ice Making Compartment

An ice maker may be implemented as a special compartment 10.

Special Containers

Containers 20 may be provided independent from the unit 100 for personaluse. This allows people to prepare and package lunch boxes ahead of timeand keep them refrigerated at home until they go to work next morning.Once at work, the container 20 is put back into the unit with the properprogramming. Special container bags may be provided to allow for thesafe transport of containers 20 while maintaining temperature and otherenvironmental conditions.

Prepared Food Containers

Businesses may offer prepared food items (e.g., breakfast, snacks,lunches, dinners, desserts, etc.) in standardized containers 20. Foodproviders may attach RFID chips (or similar technology) to containers 20that store the food storage and preparation program for each individualpackage. When the container 20 is inserted into a unit 100, theprocessor 150 reads the RFID information and preferably automaticallyexecutes the correct food storage program (e.g., keep it at a certaintemperature). Before users consume the items, they preferably activatethe food preparation program and the unit automatically thaws, warms,heats, or otherwise prepares the food in their compartment as directedby the program.

Lists of Alerts

Possible user alerts include, but are not limited to:

-   -   compartment locked/unlocked;    -   container inserted/removed;    -   storage duration expired;    -   bad food detected;    -   cleaning process complete;    -   cooking, refrigerating and freezing complete;    -   begin process, end process;    -   timer, proper temperature or pressure reached;    -   temperature too low/high;    -   humidity too low/high;    -   pressure too low/high;    -   other sensor readings low/high;    -   unauthorized access attempt;    -   power outage detected at restart;    -   error messages; and    -   refill compartment (e.g., in vending scenarios).

Methods of Heating Compartments

Methods of heating compartments 10 include, but are not limited to:

-   -   Hot air;    -   Electrical heating of surfaces;    -   Induction heating;    -   Microwave heating; and    -   Warming lamps.

FIG. 11 is a schematic diagram illustrating a unit 100 with 40 small and20 large compartments 10, with doors 180 for each compartment and with amechanical or electronic input pad 190 for access control (shown betweenthe large and small compartments). This control can be located anywhereincluding, but not limited to, on the unit, in between one or more unitsor on a wall near the unit or units.

FIG. 12 is a schematic diagram of a bill changer and credit card reader200 that may be incorporated into a unit 100 to allow the unit 100 tofunction as a vending machine. Like the unit 100 shown in FIG. 11, thebill changer and card reader 200 may be positioned on the unit or units,in between one or more units or on a wall near the unit or units. Theletters and numbers in the bill changer and card reader have beenexaggerated for ease of illustration.

The compartments 10 are preferably able to accept containers and/orinserts that come with a lid or bag for soups and/or liquids. The lid ofthe insert/container and the bag may optionally include a vacuum suctionnipple which will allow for the contents to be vacuum packed, by eitherusing the machines attachment or at home with a home use vacuum sealerhose. Lids may also come with a release valve (for pressurized items tobe cooked). These inserts/containers may be disposable or reusable basedon the needs of the users.

The inserts/containers with lids may be sold separately or through thevending machine depending on the build of the unit 100. This allows fora cleaner and more sanitary refrigerator, as spills will be less likelyas the food in held in an “insert” or “container” rather than in thecompartment 10 directly. Each of these compartments 10 preferably has aseparate door and allows for specific atmospheric conditions, whether itis a hot cooking area, cooling area or combination of the two. Thisprovides for a more efficient method of heating and cooling or both atthe same time.

A refrigeration unit 100 may also be incorporated with a microwave orconvection oven unit with compartmentalized access as well. This may bea separate unit or an all-in-one unit depending on the size a buyerwishes to purchase. This unit 100 would allow multiple people to heatand cook food items at the same time. The present invention may alsoincorporate moving robotic abilities to move items from one compartment10 to another. For example, a dirty box alerts the machine, and arobotic arm or belt could move the container to a dumping area andrinsing compartment to clean and sanitize the container 20.

FIG. 13 shows schematic front and rear views of a compact and integratedunit 200 that incorporates an induction cook top 300. The unit 200includes a housing 310 that houses compartments 10 in a stackedarrangement. The induction cook top 300 is positioned on top of thestacked compartments 10, and utilizes an induction heating element,similar to the induction heating element shown and described above inconnection with FIG. 7.

For purposes of illustration, four compartments labeled “pizzacompartment,” refrigerator compartment #1,” refrigerator compartment #2”and “freezer compartment” are shown as part of unit 100. However, itshould be appreciated that any type of compartment 10 discussed aboveand any number of compartments 10 can be used. The “pizza compartment”is preferably a refrigerator compartment that has been sized toaccommodate a full size pizza.

The compressor 310 used to cool the refrigeration/freezer compartments10 is preferably located at bottom rear of the unit 200. The unit 200optionally includes retractable wheels 320 and a retractable handle 330for transporting the unit 200. In addition, the unit 200 can optionallyinclude a retractable folding hood system 340, and foldable surfaces 350that can be folded up to provide work surfaces.

The induction cook top 300 preferably includes a photoelectric sensor360 positioned below the top surface of the induction cook top 300. Thephotoelectric sensor 360 is used to detect the color of customizedcookware that is designed to be used with the unit 200, as will beexplained in more detail below. The unit 200 also includes a processor370, whose functionality will be explained in more detail below.

FIG. 14 is a schematic view of the front of unit 200 with the foldablesurfaces 350 in a deployed (folded up) configuration. The foldablesurfaces 350 provide a work station when in the deployed configuration.

FIG. 15 is a schematic view of customized cookware 400 that is adaptedto be used with the unit 200 of FIGS. 13 and 14, in accordance with oneembodiment of the present invention. The cookware 400 is preferably madewith a material that exhibits high magnetic permeability so that it willwork with the induction cook top 300. Examples of materials that can beused for the cookware 400 include, but are not limited to, metglas,iron, ferritic stainless steel, martensitic stainless steel or any othermaterial suitable for use with an induction cook tip 300.

To improve heat conduction, the base 410 of the cookware 400 can beoptionally made of a different material than the sides 420 of thecookware 400. For example, the base 410 can be made of iron and thesides 420 can be made of aluminum to allow heat to dissipate moreuniformly across the cookware 400. Other combinations of materials withmagnetic permeability and heat conduction properties can be used toallow for the design of cookware 400 tailored for specific cookingrequirements.

The base 410 of the cookware 400 is preferably coated with an insulatinglayer 430 (e.g., a silicon layer) to act as a heat insulator and scratchprotection. This will allow the cookware 400 to be placed on delicatesurfaces without damaging those surfaces, even when the sides 420 andbase 410 of the cookware is hot. The insulating layer 430 may bepermanently affixed to the base 410 or it can be removably affixed tothe base 410.

The insulating layer 430 is preferably between 0.5 mm and 2 mm thick,and is dyed such that it exhibits one of multiple predetermined colors.The color chosen for the insulating layer 430 will trigger apredetermined cooking program in the unit 200 when the cookware isplaced on the induction cook top 300.

Although the shape of the cookware shown in FIG. 15 corresponds to afrying pan or saucepan, it should be appreciated that any shape or typeof cookware be used (e.g., saute pans, saucepans, French skillets,stockpots, etc.) as long as it incorporates the features/specificationsdescribed above.

When the cookware 400 is placed on the cook top 300, the photoelectricsensor 360 detects its presence and also detects the color of theinsulating layer 430 on the bottom of the cookware 400. In one preferredembodiment, a predetermined cooking program is initiated based on thecolor of the insulating layer 430 detected by the photoelectric sensor360. As an illustrative example, a red insulating layer could triggerthe following cooking program: (1) heat the cookware 400 to 350 degrees;(2) maintain that temperature for 10 minutes; (3) shut down the heatingelement; and (4) send a message to connected devices (e.g., smartphones)that cooking is finished. Other colors can trigger other cookingprograms. For example, a yellow insulating layer could trigger a cookingprogram designed to warm up a pizza, while a blue insulating layer couldtrigger a cooking program designed to grill meat. The various cookingprograms would be programmed into the processor 370 or stored in memory(not shown) that is accessed by processor 370.

The photoelectric sensor 360 could optionally be combined with othersensors (not shown) to trigger a reading from the photoelectric sensor360. Examples of other sensors that could be incorporated into the cooktop 300 include, but are not limited to: (1) pressure sensors thatdetect when a cookware 400 is placed on the cook top 300; and (2)magnetic sensors that are activated when magnetically permeable materialis placed on the cook top 300.

The cook top 300 can optionally include LED lights (not shown)integrated into the cooking surface that indicates the status of theunit 200 via predetermine colors and visual effects. For example, theLED lights can be linked to the different cooking programs that aretriggered by the different color insulating layers 430 on the cookware400 (e.g., red LEDs are displayed when the “red” cooking program isactivated, green LEDs are displayed when the “green” cooking program isactivated, etc.).

The LED effects could also be linked to the status of a cooking program.As examples: (1) when a cooking program starts and the induction cooktop 300 is heating up the cookware 400, the LEDs may display a “running”effect; (2) when the cookware 400 has reached the target temperature,all the LEDs may be constantly on; (3) when the cooking program hascompleted, all the LEDs may start blinking; and (4) when no cookingprogram is active, all LEDs are off. These are merely examples of howthe LEDs can be used to display status. The effects used, number of LEDsturned on, colors displayed, etc., may be customized as desired for anygiven cooking program or other function of the unit 200.

The unit 200 may optionally include proximity sensors 380 and theprocessor 370 may be programmed to detect the presence of individuals inproximity to the unit 200 based on signals from the proximity sensor.The processor 370 may be programmed to shut down the cook top 300 if anindividual is not detected by the proximity sensor 380.

An optional CO₂ sensor 390 and an optional smoke sensor 395 may bepositioned on the cook top 300 or in proximity to the cook top 300 fordetecting burning food. The processor 370 may be programmed to shut downthe cook top 300 based on signals from the CO₂ sensor 390 and/or smokesensor 395.

The processor 370 is in communication with the compartments 10, thecompressor 320, the induction cooktop 300, the photoelectric sensor 360,the CO₂ sensor 390 (if used), the smoke sensor 395 (if used) and anyother sensors and user interfaces incorporated into the unit 200. Theprocessor 370 is programmed to execute all of the various control andmonitoring functions of unit 200. It also integrates any wired orwireless communication devices used by operators to control and/ormonitor the unit 200 via an application interface on the communicationdevice. For illustrative purposes, the processor 370 is shownschematically attached to the side of the unit 200. However, theprocessor 370 can be attached anywhere on or within the unit 200.

The application interface is used by wired or wireless communicationdevices and communicates with the processor 370 and allows operators tointeract with the unit 200. The application interface is preferable awireless interface implemented on a mobile device.

The application interface allows operators to interact with the unit 200to reconfigure cooking programs, change alarm and event thresholds,change the number and type of sensors used by the unit 200, manageauthorized mobile devices and user authorizations, and enable specialfun features of the unit 200, such as LED light shows. Multiple mobiledevices may communicate simultaneously with the unit through theapplication interface app. In addition, all preconfigured cookingprograms can be changed and new cooking programs can be added throughthe application interface.

The application interface is preferably configured to send events andalarms to all mobile devices that are configured to receive such eventsand alarms. Examples of events and alarms that can be sent include, butare not limited to: (1) cooking program has started; (2) cooking programhas ended; (3) cooking program was terminated for some reason; and (4)please turn meat.

An optional interface module 396 on the unit 200 allows connection of afood/meat temperature probe (not shown). The cooking programs can bemodified to consider input from the food/meat temperature probe. Forexample, the program may shut down the inductive cook top or reduce theheat and send a message when the food/meat probe indicates apredetermined temperature. In addition, other probes/sensors may beintegrated through the interface module 396. Examples include, but arenot limited to, humidity sensors or pressure sensors to measure humidityand/or pressure inside the cookware 400.

Any probes and/or sensors can be connected to the interface module 396via wired connections or via wireless connections (e.g., Bluetooth orWiFi). Further, the processor 370 can be optionally programmed toreconfigure stored cooking programs on the fly based on input from anysensors being used, and thus the processor 370 would be able to controlthe preparation of meals automatically.
